SIDE FRAME.

Application filed May 5, 192-5. Serial No. 28,094.

This invention relates to side frames for railway car trucks, and more partlcularly to such side frames formed from integral blanks of sheet-metal folded upon themselves.

One of the principal objects of the invention, generafly considered, is the formation of wrought metal side frames from blanks folded upon themselves and riveted along diagonal lines adjacentthe lower portions thereof with drainage openings provided between said rivets for minimizing rusting and consequent deterioration of the frame.

An object of my invention is the provision of a pressed metal car truck side frame in which spaced side wall portions are provided adjacent their lower edges with downwardly disposed connecting flanged portions so shaped or corrugated that they are adapted for connection by rivets or the like at their contacting portions, leaving spaced portions between said connected portions serving as drainage openings for the elimination of moisture and the prevention of rust and corrosion.

Another object of the invention is the provision of sheet-anetal side frames formed with spaced wall portions, said wall portions being formed with a relatively central window opening, the periphery of said window opening being framed by inwardly disposed fianges from said wall portions, wear plates connecting the inner and outer walls of said frame, extending over a portion of said flanges, and united to said frame by rivets, some of :which extend directly through the outer and inner side wall portions of the frame and corresponding flanged portions of the wear plate, and others of which extendthrough diagonally disposed flanged portions of the frame and correspondingly disposed portions of the wear plate.

Another object of my invention is the provision of a sheet-metal truck side frame formed with wear plates riveted thereto, and brake hanger brackets connected to the inner side wall of the frame adjacent said wear plates, common connecting means serving to connect portions of said wear plates and brake hanger brackets with said side frame.

Another object of my invention is the provision of wrought metal side frames for railway cars with journal box pockets formed in the ends thereof, and journal boxes with specially designed roof portions engaged in said pockets.

A further object of my invention is the provision of sheet-metal side frames formed from blanks folded upon themselves and connected by diagonal lines of 'ivets along the lower portions thereof, the ends of said frames being formed with recesses for the reception of specially designed journal boxes, said journal boxes being formed with lugs extending between flanged extensions from the side. frame and riveted thereto.

Other objects and advantages of the invent-ion, relating to the particular arrangement and construction of the various parts, will become apparent as the description proceeds.

Referring to the drawings illustrating my invention, the scope whereof is defined by the claims:

Figure l is a side elevation, partly in longitudinal section, showing the side frame embodying my invention and having con nected thereto journal boxes, wear plates and brake hanger brackets.

Figure 2 is a plan view, partly in horizontal section, on the line 2-2 of Figure 1, and partly broken away.

Figure 3 is a transverse sectional View on the line 3-3 of Figure 1, looking in the direction of the arrows.

Figure 4 is a transverse sectional view on the line 4l4 of Figure 1, looking in the direction of the arrows.

Figure 5 is a transverse sectional view on the line 5-5 of Figure 1, looking in the direction of the arrows.

Figure 6 is an end view of the frame and connected journal box, as shown in Figure 1.

Figure 7 is a horizontal s ctional view on the line 7-7 of Figure 1.

Figure 8 is a transverse sectional view on the line 88 of Figure 1.

Referring to the drawings, in which similar reference characters designate like parts in the several views, there is shown a side frame 1 formed from a single blank which is adapted for being cut from a substantially Each half of the frame 1 comprises a plurality-of top arch bar portions 2, bottom arch bar portions 3, and truck column portions The blank for the frame, after having been cut to form the parts enumerated and formed with flanges 5 framing the window opening 6, flanges 7 framing the triangular openings on opposite sides of the window opening 6, and flanges 8 along the lower edges of the lower arch bar portions 3, is then bent over on itself to form spaced side walls 9 and 10, as shown most clearly in Figure 2.

The flanges 8 in the center or extreme lower portions of the bottom arch bar portion 3 are simply inwardly extending flanges like the flanges 5 and 7. Those portions of the flanges 8, however, which are diagonally disposed on opposite sides of the central horizontal portion of the bottom arch bar portion 3, are specially cor rugated or formed with downward extensions lli, formed with. inwardly disposed bosses 0r abutment portions 12. Although four of such corrugated or abutment portions 12 are shown on each side of the window opening in the frame, I do not wish to be restricted to such a showing as any desired number may be employed.

As shown most clearly in Figure 8, the complementary halves or spaced side walls 9 and 10 of the frame are connected, besides the unitary connection where the blank is bent upon itself at the top of the frame, by rivets 13 through the abutting corrugated or embossed portions 12 on the downwardly extending portions 11 of the flanges 8. 7

On account of the embossed portions 12, as will be apparent from considering Figure 23 articularly, there are apertures l-l; left between each pair of rivets. Such apertures serve for drainage purposes and minimize the entrapment of water or the like between. the inner and outer side walls of the frame. It will be apparent that without such drainage openings any accumulation of moisture between the abutting portions of the side walls would have a rusting or deterioratii'ig effect thereon and would not dry off as quickly as desired if any large area between plates was provided for such moisture to accumulate.

The extreme outer or upper ends of the flanges 8 are curved concavely downward, as shown at 15, for the'reception of the journal boxes 16, the roof portions of which are correspondingly curved.

As shown most clearly in Figure 1, the roof portions 1'? of said jouri'ial boxes are formed double, the upper wall 18 being 1 "11 to cor pon ith h Curved not: er :5 9 he lang 8, and. the lower po tion 19 being of the usual flat formation. The portions 18 and 19 of the journal box extension thereof.

nealgaee roof are preferably connected by a bracing web 20, preferably centrally disposed, as illustrated.

Each journal box 16 is preferably provided with a lug 2l extendi-ng between the portions 11 of the flanges 8 or a triangular The lug 21 is preferably ape-rtured at 23, said aperture being surrounded by a boss portion 2%, the thickness of the lug over the boss portion 24: being substantially equal to the spacing between the downwardly extending portions.

11 of the flanges 8.

Although a boss portion is shown on the ournal box lug, the same effect might be accomplished by inwardly embossing the extension 22 ad acent the aperture 23 so that the distance between the embossed portions on 92 would approximate the thickness of the lug 21 without the provision of any boss thereon. The idea involved in this construction is the same as that illvolved in corrugating or embossing the diagonally disposed connecting portions 11 of the flanges 8, namely, the minimization of areas between overlapping portions of metal where moisture could accumulate with deleterious results.

Additional means for connecting the journal boxes 16 with the side frame may comprise upstanding flanges 25 and 26 on said journal boxes embracing the ends of the frame. The flanges 25 and 2G and the adjacent portions of the frame are preferably each formed with a corrugation 27, those corrugations in the frame gradually merging into the fiat side wall portions thereof, as shown at 28.

The window opening 6, as shown par ticularly in Figure 1, is narrowed adjacent the upper half thereof, as is usual, and provided with wear plates 29 and 30, the lower portions of said wear plates preferably overlapping the junction formed in the flange 5 where the wlidow opening 6 changes in width. The flanges 5 adjacent the wid st part of the window opening 6 are plane and extend toward each other, that is, those from the outer side wall of the frame extend toward those from the inner side wall, and vice versa. '1 he vortical flanges adjacent the narrow portion of the window opening, however, are of special construction, illustrated most clearly in Figure 2. That is, they are formed with diagonal portions 31 connecting inwardly disposed parallel portions 32 with the correspondin side wall portions of the frame. From these parallel portions extend transversely disposed flanged portions which merge with the flanges 5 of the wider portions of the window opening.

The purpose of such construction is to provide bolster side wear portions which are disposed closer together than the inner ltitl ll t) Iii and outer side walls of the frame. That is, the parallel portions 32 are disposed a shorter distance with respect to each other than the inner and outer side walls 9 and 10 of said frame. Over these specially formed flanged portions 3l-3233 are secured the correspondingly formed wear plates 29 and 30, as illustrated, the securing means therefor preferably taking the form of upper rivets 34 extending through the diagonal portions 31 of the frame and corresponding diagonal portions 35 on the wear plates, and lower rivets 36, preferably extending through longitudinally extending flanged portions 37 of the Wear plates 29 and 30 and the corresponding side walls of the frame, the lower connection being made preferably below the junction where the window opening changes in width.

On account of this construction all that is really normally necessary for connecting the wear plates to the frame, is one transversely disposed rivet 36 and one diagonally disposed rivet 84 through each flange of each wear plate. However, when the brake hanger brackets 38 are employed, it is preferable to extend the inner flange of each wear plate, as shown in dotted lines in Fig-.

ure 1, and employ a common rivet 39 for connecting a portion of the base of the brake hanger bracket 38, the flange of the wear plate 29 or 30 and the side frame.

Using the common rivet 39 for connecting these members, the wear plate 29 or 30 being embraced between the other two parts, raises the corresponding base portion of the brake hanger bracket so that the additional securing means 40, preferably take the form of rivets extending through an offset base portion 41 of the brake hanger bracket 38 and the adjacent portion of the side wall of the frame.

Because of the described construction of wear plate 29 or 30 and the mode of connection between the same and the side frame, a transverse or central wearing surface 42 is provided on each wear plate, together with side wearing surfaces 43 on the flanged portions thereof, all of said surfaces being unobstructed by rivet heads or broken by perforations or indentures so that a maxi mum wearing area is n'ovided within the limits allowed.

In. view of the foregoing, it will be apparent that an integral pressed steel side frame has been provided which is conveniently formed by folding a properly shaped blank upon itself and diagonally riveting the same at isolated points to provide drainage openings between the rivets. The wear plates on this frame are connected by rivets through rivet holes positioned in different planes and at different elevations so that maximum efficiency of riveting strength is secured as well as a freedom from rivet interference on the necessary wearing areas.

Brake hanger brackets are also connected to the frame and common riveting means serve for connecting portions thereof and the corresponding wear plates with the side frame.

The journal boxes employed with the frame have roofs of special shape so as to cooperate efliciently with the pockets provided at the ends of the frame, and journal box lugs are provided for convenient and efficient connection with the frame between downwardly extending flanged portions thereof.
